Zodiark's Codex entry what do we think about it?

[Kozh]

She lives in the Aetherial Sea, but I don't remember dialogue about harvesting from it. I was under the impression that she IS the Mothercrystal and that it contained and was powered by the souls that were sacrificed for her summoning, with the souls being completely used up specifically because she didn't sip the aether of the world.

Nah, mothercrytal is aether from the aetherial sea she harnessed and crystalized over the years after she "became the will of the star". She probably did it little by little as to not damage the Star (that much). She hide behinds it every time she called people there, so people assume that hydaelyn = mothercrystal.

I looked up the scene and she says that after she became the Will of the Star, the aether drawn there began crystalizing to create the Mothercrystal and it became the Will of the Star in her place as a "faceless, omnipotent force of nature", which is probably the truest sense of "Will of the Star" over herself and Zodiark. She doesn't say anything about doing it herself or parasiting aether.
